Abstract
The use of CFD codes has become widespread to solve the shockwave propagation problem, as they are able to successfully model explosions. Using the structured grid spherically and cylindrical charges cannot be modelled in 3D, thus remapping techniques have been developed to map spherical shockwaves from 1D to 2D and then to 3D. This method highlights the importance of the accuracy of the 1D model, which is mainly dependent on the mesh size. This study aims at finding the required division ratio for the calculation domain.
